A:Answer Funny you should ask as I just set up mine this past week.
Initially, I had the TWC Arris TG1672 Router and was getting very slow speeds from the Orbi so I got rid of the TWC router and, in its place, put in a Netgear CM600 modem.
I've got quite the set up with the Modem connected to the Orbi and the Orbi is connected to a pretty serious network switch which has a printer, Hue hub, Iris hub, a Mac, a Digital Storm PC, Sonos system, Vonage (soon to be Ooma) VoIP phone system and, finally, a Sprint Airave box connected to the switch.
On the wireless end, I've got three Smart TVs, two IPads, two IPhones, a Macbook and two cameras utilizing the Orbi Satellite.
The speed from the Orbi router and Satellite blazes. I'm now getting an average of 117.5 Mbps download and 11-16 Mbps upload from both the Orbi router and the satellite. I have the TWC 100 meg package.
The distance is impressive as well as I can connect to my home network three blocks away and this is in an older home with stucco walls which eats WiFi and cell signals for breakfast.
So, to make a long answer longer, you shouldn't have any issues once you go through the set up. If you have phone service with TWC, make sure you keep the service until you port over your numbers with the new service.
